Gas-insulated high voltage device |
(57) Gas-insulated high voltage device comprising at least one electric conductor which
is enclosed in a tubular metal enclosure (2) consisting of at least two tube sections
(21,22) arranged axially one after the other, and joined together by means of flanges
(23,24) holding between themselves a disc-or funnel-shaped support insulator (1) for
said at least one conductor, with a sealing member (4) being arranged between the
support insulator (1) and said flanges (23,24). According to the invention the sealing
member (4) comprise two sealing rings (41,42) arranged on either side of the insulator
(1) and being retained by a bridge (43) made of the same material as the rings and
surrounding the periphery of the insulator (1) (Figure 1).
